Super Soaker
Source Institutions
In this activity (page 1 of the PDF under SciGirls Activity: Bogs), learners will test cups full of potting soil, sand, and sphagnum moss to see which earth material is able to soak up the most water.
Dip Dip, Hooray
Source Institutions
Lakes, streams and other freshwater bodies are a habitat for lots of living things, big and small.
Clear Water, Murky Water
Source Institutions
How do scientists measure how clear or murky water in a lake is? How does water clarity (clearness) affect what lives in the lake?
Stick to It: Adhesion II
Source Institutions
Water sticks to all kinds of things in nature — flowers, leaves, spider webs - and doesn't stick to others, such as a duck's back.
Water Ways
Source Institutions
In this activity (on page 2 of the PDF), learners explore surface tension by adding pennies to cups which are "full" of plain water or soapy water.
Use Clues to Solve an Ice Mystery
Source Institutions
Learners explore the variables that affect the properties of ice and the places where different types of ice are found.
Moving On Up: Capillary Action II
Source Institutions
Learners explore capillary action in plants (such as plants ability to move water from roots to leaves) in an investigation called Paper Blooms.
Heat Capacity: Can't Take the Heat?
Source Institutions
Why is ocean water sometimes the warmest when the average daily air temperature starts to drop? In this activity, learners explore the differing heat capacities of water and air using real data.
Giving Water the Treatment
Source Institutions
In this ecology activity (page 8 of the PDF), learners explore how to filter contaminated water using a variety of materials.
Crumple a Watershed
Source Institutions
Learners gain an intuitive knowledge of the physical aspects of watersheds by creating their own watershed models.
Global Climate Change and Sea Level Rise
Source Institutions
In this activity, learners practice the steps involved in a scientific investigation while learning why ice formations on land (not those on water) will cause a rise in sea level upon melting.
Ocean Currents
Source Institutions
In this activity, learners will explore how density is affected by temperature and how that can create currents.
Do Plants Need Sunlight?
Source Institutions
In this activity, learners find out what happens when they cover leaves with pieces of black construction paper. This activity shows learners that plants need sunlight to survive.
Forces at the Nanoscale: Nano Properties of Everyday Plants
Source Institutions
This is an activity (located on page 3 of PDF under Nasturtium Leaves Activity) about surface tension.
Mystery of the Disappearing Cottonwoods
Source Institutions
Learners will explore the scientific mystery behind a disappearing group of trees by examining data and attempting to explain the decline.
